Covid - Vaccine emergency use applications

Pfizer (PFE) has withdrawn an application in India for emergency use authorization of the COVID-19 vaccine it developed with BioNTech (NASDAQ:BNTX), Reuters reported. That decision followed a meeting with the country's drugs regulator, which had been declining to accept the EUA without a small trial on safety and immunogenicity for Indians. In the meantime, since Pfizer applied for the EUA, India has given authorization to two much cheaper vaccines that applied later: from Oxford/AstraZeneca (NASDAQ:AZN) and from Bharat Biotech/Indian Council of Medical Research.

In the United States, Johnson & Johnson (NYSE:JNJ) has applied to the FDA for emergency use authorization for its single-shot COVID-19 vaccine. If approved, it would be the third such vaccine to get an emergency OK from the Food and Drug Administration, joining the vaccines from Pfizer/BioNTech and Moderna. Last week, Johnson & Johnson's vaccine was found to be 66% effective in protecting against the virus in a global trial.
The vaccine is eagerly anticipated, as the single-shot regimen points toward a far simpler distribution path than that of the vaccines from Pfizer (NYSE:PFE) and Moderna (NASDAQ:MRNA), each of which calls for two shots given weeks apart. The J&J vaccine will also ship at 36-46 degrees Fahrenheit, vs. Pfizer's ultra-cold shipping (-112 to -76 degrees) or Moderna's (-13 to 5 degrees).

Tencent Music choosing banks for $5B Hong Kong IPO within year

Tencent Music Entertainment (NYSE:TME) - the online music arm of China's Tencent Holdings (OTCPK:TCEHY) - has reportedly selected banks to help lead a planned listing in Hong Kong for up to $5B, to come within the year. JPMorgan Chase (NYSE:JPM) and Morgan Stanley (NYSE:MS) have been chosen to lead the offering, and more banks could join, according to media reports. Tencent Music raised $1.1B in its U.S. IPO in late 2018, and has nearly doubled its value since - but a Hong Kong listing would take advantage of a hot capital market.
